I still don't know what you did to install it. However, I guess you extraced the archive on your server and added a plugin_load line to your autoexec.cfg. That could cause the errors, because it gets loaded twice (via the vdf file and autoexec.cfg).

no, I did not create a autoexec. I installed the server itself (csgo) from the webinterface. After that, i extracted the downloaded archive on my server. That's all. It may crash because of GLIBC 2.17 or later is required ?

I'll create a support ticket on ngz to see if it's the problem. However, i noticed on another fresh installed that 9 files are not transfered to my ftp which are the .exe files in \python\addons\source-python\Python3\distutils\command. It's the wininstall files.

//edit

some more logs after the update today, dunno if sth important is in it

I did that several times already. I tried it with a standard install and also with a deleted vdf, aswell as trying to load the plugin with deleted vdf via server config (plugin load addons/source-python).

well i got almoust same problem but with css , and i reinstalled whole steam (ofc im using dedicated root access) after that it worked .. i guess its bugged there or smth if its load twice .vdf file .. this is really strange :S if you can remove server and reinstall it i would give it a try
